Eagle Ford 351W 4.000in Crank 6.200in H-Beam -5cc Flat Top 4.030in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, built for serious performance in Ford 351W engines. What you get in this kit is a forged 4.000-inch stroke crankshaft made from 4340 steel, a set of 6.200-inch H-beam connecting rods, and 7/16-inch ARP 2000 bolts to secure them. It also includes forged 2618 JE pistons with a -5cc flat top dish, designed to fit a 4.030-inch bore, along with plasma-moly file-fit piston rings. To finish it off, King XP rod and main bearings are included to ensure smooth operation and durability.

This assembly is engineered for the most demanding applications, including those using exotic fuels, heavy nitrous oxide injection, or high boost levels. The 4340 forged steel crankshaft and H-beam rods offer a strong foundation for high-horsepower builds, while the JE pistons are well-known for their strength and reliability under extreme stress. The ARP 2000 bolts are a significant upgrade, providing superior clamping force compared to standard fasteners, which is crucial for maintaining integrity at high RPMs and under heavy loads. The plasma-moly file-fit rings allow for precise gap setting, which is important for optimal sealing and performance in competition engines.

When building a high-performance or competition engine, a robust rotating assembly is key. This Eagle kit provides the core components needed to build a powerful and durable powerplant. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning procedures to get the most out of this heavy-duty rotating assembly.
